[SQL] Does PostgreSQL support job?

[Daniel Caune]

Hi,   I try to find in the documentation whether PostgreSQL supports job, but I miserably failed.  Does PostgreSQL support job?  If not, what is the mechanism mostly adopted by PostgreSQL administrators for running jobs against PostgreSQL?  I was thinking about using cron/plsql/sql-scripts on Linux.   Thanks (Tom Lane J)   -- Daniel CAUNE
